It includes a new generation of specially developed and patented dyes in a robust and more open carrier matrix for faster transition, allowing them to be clearer indoors, darker outdoors, and quicker to react than previous generations.<\/p>\n\n\n\n<p><strong>Speed Matters<\/strong><\/p>\n\n\n\n<p>Patients frequently buy a range of prescription lenses: clear, sunglasses, and more recently, blue light protection glasses. However, having many prescription eyeglasses is pricey and can be an inconvenience to some.<\/p>\n\n\n\n<p>When people are indoors, they typically want their lenses to be clear. When stepping outdoors, their eyes perceive light and glare, and they want sunglasses that provide comfortable protection.<\/p>\n\n\n\n<p>Early generations of photochromic glasses were not dark enough or were too slow to clear when coming indoors. Slow fade-back speed is a visual inconvenience, as it\u2019s difficult to see indoors with dark lenses, and in social situations it can be embarrassing.<\/p>\n\n\n\n<p><strong>Fast transition is important to patients:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>For many patients, quick clearing indoors is the most important feature in photochromic lenses.[2]<\/li><li>Slow change from dark to light is the most common pain point for photochromic lens wearers.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"624\" height=\"137\" src=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX1.jpg\" alt=\"\" class=\"wp-image-7353\" srcset=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX1.jpg 624w, https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX1-600x132.jpg 600w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 624px\" \/><\/figure>\n\n\n\n<ul class=\"wp-block-list\"><li>\u201ctoo slow to go clear\u201d was the most cited technical performance reason for not purchasing photochromic lenses.[3]<\/li><li>In the same study, 100% of experienced photochromic lens wearers noted \u201cclearing up fast inside\u201d is an important characteristic, even more so than darkness or indoor clarity.<\/li><\/ul>\n\n\n\n<p>ZEISS collaborated with Colts Laboratories, an independent ophthalmic lens testing company in the USA, to measure the photochromic properties of PhotoFusion\u00ae X lenses and compare them to the latest lenses from other brands.<\/p>\n\n\n\n<p>The Colt\u2019s independent tests lead to the following conclusions:<\/p>\n\n\n\n<p><strong>PhotoFusion\u00ae X Grey<\/strong> is up to 1.5 times faster to clear than the most common photochromic brand\u2019s latest generation grey(14) .<\/p>\n\n\n\n<p><strong>PhotoFusion\u00ae X Pro Grey<\/strong> is up to 4.5 times faster to clear than the most common photochromic brand\u00b4s latest generation grey., comparing average fade-back speed to an interpolated time to 80%T. [4]<\/p>\n\n\n\n<p><strong>PhotoFusion\u00ae X Brown<\/strong> was twice as fast as the same brand\u2019s latest brown. [5]<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-artificial-blue-light-a-21st-century-problem\"><strong>Artificial Blue Light: A 21st-Century Problem<\/strong><\/h2>\n\n\n\n<p>Modern artificial light sources such as LED lights and the usage of digital devices like computer screens, tablets, TVs and cell phones are increasing the eyes\u2019 exposure to artificial blue light. While longer wavelength blue light, that that from the sun, can help us stay alert and awake, shorter wavelengths, like those from digital devices, can generate visual irritation and may even harm the eyes. In addition, blue light is thought to contribute to digital eye strain, causing symptoms like blurry vision and visual discomfort.[7]<\/p>\n\n\n\n<p>Online concern is propelling blue light lens sales. People are looking for &#8220;blue light glasses&#8221; online at a greater rate than before. Google searches for blue light glasses have increased five-fold in two years (figure 1).[8] In 2020, the term (blue light glasses) outpaced photochromic lenses searches.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"624\" height=\"480\" src=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX2.jpg\" alt=\"\" class=\"wp-image-7354\" srcset=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX2.jpg 624w, https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX2-600x462.jpg 600w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 624px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-uv-radiation-a-hidden-danger-for-our-eyes\"><strong>UV Radiation- A Hidden Danger for Our Eyes<\/strong><\/h2>\n\n\n\n<p>UV radiation is not visible to the human eye but poses potential risks to eye health. Without protection, UV radiation may damage anterior ocular structures and the skin around the eyes.<\/p>\n\n\n\n<p><strong>Eyelids and periorbital skin:<\/strong><\/p>\n\n\n\n<p>UV induced eyelid damage is common. Experts usually recommend sunscreen on the eyelids to prevent damage, but people often do not take this safety measure because sunscreen can cause eye irritation.<\/p>\n\n\n\n<p><strong>UV radiation may cause several chronic skin conditions:<\/strong><\/p>\n\n\n\n<p>\u2022 Eyelid photo-aging, which makes the skin thicker and generates prominent wrinkles;<\/p>\n\n\n\n<p>\u2022 Sebaceous gland damage;<\/p>\n\n\n\n<p>\u2022 Skin cancer on the eyelid<\/p>\n\n\n\n<p><strong>Lens:<\/strong> As the eye ages, protective pigments in the lens are converted into pigments that react to UVR, further damaging lens proteins and the lens\u2019s outer layer. When damage accumulates, the lens can develop a cataract, severely compromising vision.<\/p>\n\n\n\n<p><strong>Iris:<\/strong> Melanoma tumors are the most common cancer of the eye, and evidence suggests that UVR is one of its leading causes.[9]<\/p>\n\n\n\n<p><strong>Retina:<\/strong> In young people, some longer UVR wavelengths may reach the retina and cause photochemical damage.<\/p>\n\n\n\n<p>Because of this ZEISS provides sunglass-level UV protection in all clear ZEISS lenses. ZEISS PhotoFusion X lenses provide sunglass-level UV protection up to 400 nm in both the clear and activated states. This protection is built into ZEISS BlueGuard materials. This means PhotoFusion\u00ae X lenses provide the same UV blocking as premium sunglasses.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"624\" height=\"495\" src=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX3.jpg\" alt=\"\" class=\"wp-image-7355\" srcset=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX3.jpg 624w, https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2022\/05\/PFX3-600x476.jpg 600w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 624px\" \/><\/figure>\n\n\n\n<p>Premium sunglasses typically offer full UV protection to 400 nm; however, people may not own a pair and often do not wear them on cloudy days. A Vision Council of America survey found only 21.2% always wear sunglasses when outdoors.[10]<\/p>\n\n\n\n<p>PhotoFusion\u00ae X are everyday lenses, for use indoors and outdoors, so wearers have them on all the time, providing more reliable and consistent UV protection.
